Study of heavy-flavor quarks produced in association with top-quark pairs at s = 7??TeV using the ATLAS detector

Original language description

Using a sample of dilepton top-quark pair (tt) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of tt+b+X and tt+c+X, collectively referred to as tt?+?HF. The data set used corresponds to an integrated luminosity of 4.7??fb1 of proton-proton collisions at a center-of-mass energy of 7 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The presence of additional HF (b or c) quarks in the tt sample is inferred bylooking for events with at least three b-tagged jets, where two are attributed to the b quarks from the tt decays and the third to additional HF production. The dominant background to tt?+?HF in this sample is tt+jet events in which a light-flavor jet ismisidentified as a heavy-flavor jet.
